About

Patients with implanted cardiac devices who meet appropriate entrance criteria undergo clinically indicated Magnetic Resonance (MR) Imaging Studies using an established safety protocol.

Full description

This prospective cohort study to use an established MRI device safety protocol to decrease the risk of clinically indicated MR imaging in patients with implantable cardiac devices. All devices will undergo a complete interrogation and testing of thresholds, sensing, battery voltage and impedances prior to and following imaging. Pre-MRI, devices will be programmed to setting that will ensure MRI safety. During imaging, patients will blood pressure, heart rate and O2 sat level will be monitored continuously.

Enrollment: 1,509 patients

Sex: All

Ages: 9+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients with an emergent or absolute need for MR imaging and PPM or certain ICD's

Exclusion criteria

• Pacemaker dependent patients with ICD's
• Patients with other contraindication to MRI
